To confirm the association between ETAR and ZEB1, we performed an analysis from The Cancer Genome Atlas (TCGA) database of 535 miRNA/mRNA matched high-grade serous ovarian cancer (HG-SOC) patients, which are subdivided in four subtypes (proliferative, mesenchymal, differentiated and immunoreactive) based on their specific gene expression profiles4. Here, ZEB1 is linked to ovarian serous adenocarcinoma.
